STILNOVO DIPHY 8163/6, 8164/7 ceiling LED lamp 54-76cm

Description:

STILNOVO Diphy S is an exceptional, premium-class LED luminaire designed for ceiling or wall installation, created by Mirco Crosatto. Its nature-inspired shape recalls a gently falling leaf— a subtle, almost graphic outline instead of a traditional shade. The most distinctive feature is the “disappearing lamp” effect: when Diphy is switched off, the diffuser appears almost completely transparent; once switched on, it reveals an elegant, uniform glow that sets the mood without a heavy form and without harsh, point-source glare.

Award-winning design in the world of product design

Diphy is one of the most recognisable projects in contemporary decorative lighting, appreciated in major design competitions. It is made for interiors where a single luminaire should become a strong focal point: in the living room, dining area, or a premium apartment, as well as in hotels, lobbies, restaurants and representative office spaces.

Transparent PMMA diffuser and OptiLight – why the light looks so “clean”

The key to the unique effect lies in the PMMA diffuser. The element is thermally formed and refined with microstructures and precise surface processing. Light from the central LED module is captured and guided along the diffuser’s curves, then evenly distributed. In practice, this means:

• very uniform emission without a “pixel” LED effect,
• a soft glow and high visual comfort,
• reduced hard shadows, which works perfectly in residential and commercial spaces.

Light quality: topLED, CRI 90, 2700K or 3000K

The integrated topLED source ensures stable performance and high user comfort. CRI 90 means more accurate colour rendering—wood, fabrics and finishes look more natural, which matters both at home and in hotel or restaurant projects.
Two colour temperatures are available:

• 2700K – warmer, more atmospheric, ideal for relaxation,
• 3000K – warm white, more versatile for everyday use.

Variants and codes: size and dimming type

Diphy S comes in two sizes and two control standards. When choosing a code, focus primarily on the installation and the preferred way of regulating light output:

Size approx. 54 cm

• 8166 – version with phase-cut dimming (phase dimming; typical wall dimmers)
• 8163 – version with DALI-Push dimming (automation, lighting scenes, premium installations)

Size approx. 76 cm

• 8167 – version with phase-cut dimming
• 8164 – version with DALI-Push dimming

Practical tip: with phase-cut dimming, compatibility between the dimmer and the LED load is crucial—within projects, it is worth selecting control gear designed for LED and for the luminaire’s power.

Where Diphy S works best

• Living room / lounge area – as a main decorative luminaire, creating ambience with soft light.
• Dining area – especially the larger size as comfortable general lighting above the table zone.
• Bedroom and hotel rooms – with 2700K for a calm, atmospheric mood.
• Restaurants, lobbies, offices, meeting rooms – an elegant accent and the ability to work with lighting scenes (DALI-Push).

FAQ – frequently asked questions

Is Diphy S a ceiling light or a wall light?
It is a ceiling-and-wall luminaire — it can be installed both on the ceiling and on the wall.

What is the difference between 2700K and 3000K?
2700K is warmer and more atmospheric, while 3000K is warm white — more versatile for everyday tasks.

Phase-cut: will any dimmer work?
Not always. For LED, it is best to choose a dimmer compatible with LED loads and with the luminaire’s wattage to avoid flicker or a limited dimming range.

DALI-Push: who is it for?
For premium projects and investments where integration with building automation and lighting scenes matters (smart home, hotel, office).

Is the light source replaceable?
In Diphy S the light source is integrated (topLED), which ensures a consistent lighting effect and clean aesthetics, but it is not replaceable.

How do I clean the PMMA diffuser?
Gently, using a soft cloth (microfibre) and a mild cleaner — this helps maintain clarity and prevents micro-scratches.
